Absolute Idealism

Absolute Idealism became the position through which Lewis tried to reconcile the authority of reason, moral judgment, and aesthetic value with a reality more fundamental than the world disclosed by the senses. Its Absolute promised an ultimate ground and a kind of Heaven, yet appeared impersonal and safely remote: it could be acknowledged without being met or obeyed. Lewis later understood the philosophy as a real advance in his thinking and, at the same time, as a refuge from the personal demands of theism—a refuge gradually unsettled by the very experiences and arguments it helped him interpret.

From sensory realism to the Absolute

Lewis had been a realist in the philosophical sense: he treated the universe revealed by the senses as rock-bottom reality. But he and his intellectual allies also made claims for consciousness that this material foundation could not easily support. They regarded logically disciplined abstract thought as capable of indisputable truth, moral judgments as valid, and aesthetic experience as valuable in a way more substantial than mere pleasure. Barfield showed Lewis that the combination was inconsistent. If thought were only a subjective event inside a sensory universe, Lewis could not keep making those claims for reason, ethics, and beauty without explaining how they possessed authority beyond the individual mind.

One alternative followed the sensory realist position toward a Behaviorist account of logic, ethics, and aesthetics. Lewis found that outcome literally unbelievable: his mind could not perform the act of believing it, just as a physical impossibility could not be overcome by effort. He was therefore compelled to give up realism, a position he had defended since beginning to read philosophy. The reversal was not purely abstract. He had wanted Nature to exist independently of human observation, indifferent and self-sufficient, and valued the hard particularity of things—their sheer quiddity. Abandoning realism meant surrendering that emotional as well as intellectual preference.

What remained, Lewis concluded, was that mind could not be a late-arriving by-product of an otherwise self-contained material universe. In the last resort the universe had to be mental, and human logic had to participate in a cosmic Logos. Absolute Idealism gave this conclusion a philosophical home. It was not, Lewis initially insisted, theism: he could affirm the Absolute as the ultimate reality without acknowledging a God who stood in personal relation to him.

A remote heaven and a guarded religion

The Absolute gathered together features Lewis found compelling in Idealism. It was the reality behind the shifting appearances of ordinary experience, the place where contraries were reconciled and finitude transcended. Lewis described its appeal through the image of fuller splendor behind a sensuous curtain. Emotionally, this vision was religious; intellectually, it allowed him to speak of ultimate reality while avoiding a personal deity.

That distance was the philosophy’s protection. The Absolute could be said to be there, beyond the appearances of this world, without coming here to make claims on Lewis. He later described this as a religion that cost nothing: its movement of desire rose toward the Absolute, but no answering movement of love came down, and there was nothing to fear or obey. The abstraction preserved the consolation of transcendence while removing the possibility of encounter and obligation.

Lewis nevertheless valued what Idealism gave him. Its Heaven contained the reconciliation of opposites and the hidden glory that made it the only perfectly real thing. But it was a Heaven that finite human beings could not reach: to be there, in the Absolute, was by definition not to remain oneself as an appearance. Lewis compared this condition to the virtuous pagans in Dante, living in desire without hope, and to Spinoza’s love of God without the possibility of wishing that God love him in return. He was sorry neither to have encountered this outlook nor to have passed through it. Its enduring lesson, as he later expressed it, was that Heaven’s existence mattered more than whether any of its inhabitants could reach it.

Barfield’s challenge and the limits of the system

Barfield’s influence extended beyond Lewis’s change of philosophical allegiance. Their years of disputation—sometimes conducted by letter, sometimes face to face—were not a quarrel, but Lewis remembered them as a turning point in his life. Barfield first dismantled Lewis’s chronological snobbery: the assumption that an idea was discredited simply because it had gone out of fashion. An older belief, Barfield argued, had to be examined to discover whether it had actually been refuted or had merely faded like a fashion. The same scrutiny then applied to the present, which was also a historical period and possessed characteristic assumptions it might be least inclined to defend.

That lesson helped expose a second weakness in Lewis’s former position: it could not offer a satisfactory theory of knowledge while treating the sensory world as ultimate and retaining strong claims for thought and value. Absolute Idealism resolved the contradiction by making mind fundamental rather than a late by-product. Lewis later recognized that the move also brought him nearer to theism, even though he did not then understand it that way. He suspected that he had been willfully blind to the connection. The English Hegelians, including T. H. Green, Bradley, and Bosanquet, made it possible to speak of an impersonal Absolute, or of an Absolute that knew itself through human beings, without making it clearly personal.

The system’s obscurities could even serve as insulation. When discursive thought reached contradictions, Idealists could take those failures as signs that thought operated only at the level of appearance, while reality lay elsewhere—in the Absolute. For Lewis, this could make religious language seem profound without making its object someone who might act, address, or command. His retrospective account thus distinguishes the genuine insight of idealist metaphysics from the use he made of its vagueness: it supplied both an account of ultimate reality and a defense against the consequences of believing in a personal God.

Joy brings the philosophy under pressure

Lewis’s understanding of Joy brought this philosophy into contact with his own experience. He came to see that Joy itself, considered as an event in his mind, was not what he ultimately desired. Its value lay in what it desired: something outside himself, not a state of his mind or body. He initially fitted this discovery into Idealism. Human beings, as science and ordinary perception described them, were appearances of the Absolute; their experience of Joy expressed a longing for unity with the ultimate reality from which their separate, phenomenal existence estranged them.

In this account, Joy was not a deception but a moment of especially clear consciousness. It disclosed the fragmentary character Lewis assigned to human existence and a yearning for reunion with the Absolute, even though that reunion would mean the end of the separate self. The explanation seemed intellectually and emotionally satisfying. It also marked a change in the direction of his thought: experiences and ideas that had previously moved apart were beginning to fit together. Lewis later described this convergence as a milestone that foreshadowed the point at which he would have to take his philosophy more seriously than he intended.

From the Absolute toward a personal God

Teaching philosophy as well as English made the weaknesses of Lewis’s watered Hegelianism harder to ignore. A tutor had to make ideas clear, but the Absolute resisted explanation. Was it an unknown something, or a superhuman mind—and thus, Lewis thought, effectively a Person? He concluded that Berkeley’s theistic idealism did the same work as the Absolute while offering a more intelligible account of what the ultimate mind meant. He therefore moved toward a form of Berkeleyanism, while insisting that his philosophical Spirit was sharply distinct from the God of popular religion.

The distinction preserved one last protection: Lewis imagined that Spirit projected human beings as a dramatist projects characters, so that a human being could no more meet the Spirit than Hamlet could meet Shakespeare. Calling the ultimate mind Spirit rather than God helped keep it impersonal and remote. In retrospect, the progression from sensory realism through Absolute Idealism to this philosophical God shows how Lewis’s attempts to secure objective truth also brought him closer to theism. Absolute Idealism did not itself end his resistance to personal religion, but its claims about mind, reality, and Joy narrowed the distance between the safely abstract Absolute and the God he would eventually have to consider personally.
